Also, when going to Amazon.com, I see a Kendle and a Kendle DX listed but not a Kendle 2. Is the kendle listed a Kendle 2?
Yes, I think the Kindle 1 is no longer in production.
Does anyone have additional thoughts on Nook vs Kindle? Like Wendy, thinking about buying something soon.
I have not seen the Nook but I have a Kindle 2 which I am very happy with (July birthday present). So far the kindle has provided me with hours of reading. I was not sure I would enjoy reading from a screen vs. paper but I find I enjoy it more.

Also I can carry lots of books in a small space and download more and continue reading. Not sure if Nook does the same, but many authors allow Amazon to offer their books free. This is to get you to read them and if you like them then buy more of their books. Sucked me into some really good authors and I bit and bought more of their books.

One negative is that a few of the books are poorly duplicated (reproduced) with errors. In one case it was so bad it took away from the reading enjoyment but did not stop me from reading it. Do not know if this would be the same with Nook since I do not know how they input the book?
Both reading screens appear similar if not the same so I would base our next purchase on the cost and number of books available, cell carrier coverage area, and if I had access to wifi most of the time. I also would take a good long look at the Nook as it looks like good too. The Nook does appear to have more books and the cost/book appears the same.
Bottom line I do not think you will go wrong with either unit. The only thing is the Nook is so new that all the bugs may not known but neither are the customer WoWs!
